This code works fine only when i use Hide(), this code, Show(). Have flickering here.
Without hide/show i see pretty strange thing, gridview disappear, textarea shown at top of control and height not changed (visually).

So how to invalidate without flickering, or what i can do at all here ?

I am not quite sure that I understand your issue completely. Could you please elaborate more about the panel you are talking about? How is it connected to the RadDesktopAlert? You can also share any other information I may find helpful.

The following code seems to work fine on my end:

RadDesktopAlert alert = new RadDesktopAlert();

alert.FixedSize = alert.Popup.Size = new Size(20, 30);

alert.ContentText = "Text";

alert.Show();
